ABSTRACT:
Alumina fibers whose surface is coated with zirconia to retain their identity in an alumina matrix when the mixture is sintered at temperatures needed to form a fully dense ceramic. The resulting fully dense ceramic composite shows the beneficial effects of such reinforcing fibers by having increased crack toughness.
